Fine-tuning a defense often means trying several module combinations before finding one that suits the next enemy wave. Shop purchases are free in this modified version, allowing players to obtain available resource packs without paying their listed prices. That makes experimenting with elemental bonuses, splash damage, critical strikes, and income-focused setups more convenient. The modification doesn't assemble effective builds automatically, however. Tower placement, changing routes, and enemy abilities still determine whether a particular strategy can protect the base.
